ABSTRACT:
A membrane switch comprises an insulating substrate on the surface of which thin-film-like electrodes are formed with a connecting lug section provided integrally at one end of the substrate. Thin-film-like conductive layers continuing from the electrodes are extending up to the connecting lug section and the extended end portions of the conductive layers compose a connecting terminal section.
